Experimental observation of multiple topological nodal structure in LaSb2
Unconventional fermions in the immensely studied topological semimetals are the source for rich exotic topological properties. Here, using symmetry analysis and first-principles calculations, we propose the coexistence of multiple topological nodal structure in LaSb 2 , including topological nodal s...
